Question

这个问题在这里已有答案：

• sql.h not found when installing PyODBC on Heroku 4个答案

当我尝试使用依赖项文件requirements.txt推送Updated Flask Web应用程序时，我收到以下消息，这是一个让我困惑的地方。我看到它在本地目录中查找文件并找不到它。我使用Windows机器。

在输出的第一行，它告诉你它正在尝试构建pyodbc，这是python围绕odbc的包装器。为此，需要sql.h文件，它定义了一系列通过odbc进行数据库访问的函数和类型。 该文件不在您的构建路径中，因此它在抱怨。 sql.h通常是windows sdk的一部分，所以检查你是否有这个。 sdk通常在

C：\ Program Files（x86）\ Microsoft SDKs \ Windows \ vx.y \ include

如果您没有安装sdk，可以从Microsoft（免费）下载。
